# Changelog

All notable changes to this project are documented in this file.

## [0.1.1] - 2026-09-18

### Added

- **Container-aware behaviour.** `isContainer()` detects Docker / Kubernetes /
  Podman (`.dockerenv`, `/run/.containerenv`, `KUBERNETES_SERVICE_HOST`,
  `/proc/1/cgroup`), overridable with `DSH_FORCE_CONTAINER=0|1`. Inside a
  container the plugin still reports versions but refuses to stage or apply —
  the image is the update unit — and the panel says so instead of offering
  buttons that could not work.
- **Cross-platform relaunch.** `resolveRelaunchCommand()` resolves the `dsh`
  shim per platform (`<prefix>/dsh.cmd` on Windows, `<prefix>/bin/dsh` on POSIX)
  instead of assuming a Windows layout.

### Fixed

- **Panel channel dead on harness ≥ 0.1.5 (`405 Method Not Allowed`).** The
  browser half posted to `/autoUpdate/<endpoint>`, a channel the host half
  published with `ctx.connection.rpc.handle('/autoUpdate', …)`. On dsh 0.1.5
  that call throws `cannot get property "webServer" without inject` from inside
  the connection service — `register()` ends in
  `owner.effect(() => owner.webServer.register(route))`, where `owner` is the
  connection service's own context, which never declares `webServer`. The throw
  was swallowed by the plugin's own `try/catch`, so the route was never
  mounted, every panel request fell through to the web-server fallback, and the
  card sat on "—" forever while the plugin looked installed.

  The channel is now an ordinary `webServer` prefix route at `/auto-update`
  (registered through `ctx.effect`, so it still unloads with the plugin fiber),
  and `static inject` gained `webServer`. `/auto-update` is deliberately not
  under `/plugins/`, which the harness already owns for client-module
  delivery. Host/Origin and browser-session checks are preserved by calling
  `ctx.connection.requestRejection(req)`; that method reads no other service,
  so it does not hit the inject guard.

- **Windows EBUSY on update apply.** The detached helper ran `npm install -g`
  with its working directory set to the harness install root. On Windows a
  directory that is a process's current working directory cannot be renamed,
  and npm swaps the old `@deepseek-ai/dsh` directory by renaming it — so the
  apply always failed with `EBUSY: resource busy or locked`, and no retry/backoff
  helped because the cwd never changed. The helper now runs npm from a neutral
  temp directory, removing that self-lock.
- **Double-apply concurrency.** A pending manifest rebound by a second harness
  instance could spawn two apply helpers that run `npm install -g` at the same
  time. The helper now takes an exclusive pid-owned lock (`apply.lock`, stale
  locks reclaimed) so only one helper touches the global install at a time.
- **Idempotent apply.** If the target version is already installed, the helper
  records success and clears the pending manifest instead of re-running npm.

### Docs

- **Corrected the marketplace claims.** The README described the plugin as
  listed on an "official DeepSeek Harness plugin marketplace" and documented a
  *Settings → Plugin Market* install flow. No such surface exists in the
  harness — dsh ships no marketplace code at all, and the market UI belongs to
  the separate community plugin `dsh-plugin`. The README now names
  [dsh-plugin.org](https://dsh-plugin.org) as the community market and explains
  that its UI has to be installed first.
- **Removed the dead npm install path.** The npm version badge pointed at a
  package that does not exist on the registry, and
  `dsh plugin add dsh-auto-update` failed for the same reason. The badge is now
  the dsh-plugin.org "listed" badge, and the install instructions use the
  `github:` specifier the market itself publishes.

## [0.1.0] - 2026-08-20

- Initial release. The harness can now update itself: checks npm for a newer
  `@deepseek-ai/dsh`, stages the tarball in `$DSH_HOME/updates/`, and applies
  it on harness exit or via an "update & restart" action from the web panel.
- Registered as an installable bundle so it activates with `dsh plugin add`.
- Ships a browser panel (check now / update & restart / cancel stage) and an
  English README.
